About Pass Rad Tech
Pass Rad Tech is one study site for the imaging registries: Radiography, CT, MRI, nuclear medicine, and sonography physics — as separate courses you buy only when you need them. Every course teaches each fact aloud with a memory hook, drills it with explained answers, and tests you with review tests drawn from the same question bank you drill.
